DIAGNOSIS
STEP 1. Check the TCM terminal voltage and frequency.
[C-37 TCM connector (vehicle side, connected)]
Check that the voltage between C-37 terminal No. 49 and C-38
terminal No. 13 or C-38 terminal No. 26 is 0 V, and then check
the frequency of C-37 terminal No. 38.
⦆
At D range, and the engine speed is 700 r/min: Approx. 353
Hz
Q:Is the check result normal?
YES:
Go to Step 8.
NO:
Go to Step 2.
STEP 2. Check the power supply and sensor ground.
[B-109 input shaft speed sensor connector (vehicle side,
disconnected)]
⦆
With the ignition switch ON: Terminal No. 3 to terminal No. 1
→
Battery positive voltage
Q:Is the check result normal?
YES:
Go to Step 3.
NO:
Go to Step 4.
STEP 3. Check the wiring harness between the input shaft
speed sensor and TCM.
Check for continuity between B-109 input shaft speed sensor
connector terminals and C-37 TCM terminals.
⦆
Between B-109 terminal No. 2 and C-37 terminal No. 38:
Continuity exists.
When the continuity check result is OK, check that the wiring
harness is not shorted to the body and other wiring harness.
Q:Is the check result normal?
YES:
Replace the input shaft speed sensor with the one
of the same transaxle of the same model. Then go to Step
5.
NO:
Repair or replace the failure section, and then go
to Step 8.
STEP 4. Check the path between the ignition switch and the
input shaft speed sensor.
⦆
Check the wiring harness for an open/short circuit between the
ignition switch and B-109 input shaft speed sensor connector
terminal No. 3.
⦆
Check for a blown fuse.
Q:Is the check result normal?
YES:
Go to Step 6.
NO:
Repair or replace the failure section.

AUTOMATIC TRANSAXLE DIAGNOSIS
STEP 5. After replacing the input shaft speed sensor, drive
the vehicle for a while, and then check the DTC again.
Q:Is the check result normal?
YES:
Replace the input shaft speed sensor.
NO:
Replace the TCM.
STEP 6. Check the wiring harness between the input shaft
speed sensor and TCM.
Check for continuity between B-109 input shaft speed sensor
terminals and C-37 TCM terminals.
⦆
Between B-109 terminal No. 1 and C-37 terminal No. 49:
Continuity exists.
When the continuity check result is OK, check that the wiring
harness is not shorted to the body and other wiring harness.
Q:Is the check result normal?
YES:
Go to Step 7.
NO:
Repair or replace the failure section.
STEP 7. Check the TCM connector pin terminal and the
connection status.
Q:Is there a failure point?
YES:
Repair or replace the failure section.
NO:
Replace the TCM.
STEP 8. Drive the vehicle for a while.
Check that the normal code is displayed.
Q:Is the check result normal?
YES:
The procedure is complete.
NO:
Replace the TCM.
